How to Break a BIOS Password?

Methods of breaking password for Desktop PC and for laptop is quite different. We would explain each.

Break BIOS Password for Desktop :

If it's a desktop PC, erasing the cmos memory will usually clear it.

Steps:

1. Power off the computer and make sure that it is unplugged.

2. Open up your computer case. You need physical access to the motherboard to complete this procedure.

3. Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery.

4. CAREFULLY remove the CMOS battery and leave it out for about 120-180 seconds. This will flush the CMOS memory which stores the BIOSpassword and all other configuration. (See Warnings)

5. Set the battery back into place and power on the computer.

6. The computer should then warn you that the CMOS configuration couldnot be found. You can either reconfigure it yourself or restoredefaults. Restoring the default configuration should be fine.

7. You will notice that the BIOS password has been cleared and you canboot without it. You may reset the BIOS password to something else bygoing into the BIOS configuration and setting a new User Password.

Alternate Methos: (More Dificult)

Remove a jumper: There's a jumper on your motherboard that you'll needto identify and remove. Most motherboards make your job easier byactually labeling the correct jumper as "BIOS config" or somethingsimilar. (it looks like a small plastic thingy on 2 pins with 1 pinbeside it, within a 1" of the battery). If you're having troublelooking for it, look in the motherboard manual.After you have found it,carefuly pull straight up on it, and place it on the 2-3 pins(it was onthe 1-2 pins). With the battery removed and the jumper moved, turn thecomputer on, and check to see if you can get into the bios. If you areable to, turn the computer off, put the jumper back on pins 1-2, andput the battery back in. Lastly put the case together and you are done.

Note: Don't forget to configure the BIOS (if you know how) after thisprocess. If you you don't know how, just hold the "delete" button whenstarting your PC and when the blue screen appears, find the load safedefaults settings and press:

* ENTER button

* Y button

* F10 button

Break BIOS Password for Laptop :

Remember that laptops can be trickier, especially if it's a newermodel. If it has a security chip on the motherboard forget about it.You either have to physically remove the chip or contact the mfg forthe "master" password. If you can boot up off of a cd or floppy try anyof these methods:

1. Create a Win98SE bootable media "or anything that lets you boot into MS-DOS" and boot off of it.

If your system boots but the BIOS password is still in place, there areseveral programs you can load that are designed to crack the passwordsor clear them altogether. The encryption on BIOS passwords is not verycomplex. Following are links to a few of these free programs:
